Adaptive Output-Feedback Control of Systems with Output Nonlinearities

摘要

For a class of single-input single-output nonlinear systems with unknown constantparameters, we present a direct model-reference adaptive control scheme, which requires only output, rather than full-state, measurement. The nonlinearities are not required to satisfy any growth conditions. The assumptions on the linear part of the nonlinear system are the same as in the standard adaptive control problem for linear systems, which now appears as a special case of the nonlinear problem solved in this paper.
